Application filed January 12, 1911. Serial No. 602,204.

ZY) all whom 'it may concern: VBe, it known that I, JonN M. Fiumi-ins, a citizen of thel UnitedY States, residingl at Buiahnin the county ot' llrie and Slate ot' and useful Improvements in Radiators, ot' which the following isv a specification.

This invention relates to 'adiators ot the class usually employed for cooling the water of automobile gasolene engines although thesalne can be used for other ypui-poses.

The object of this invention is the production of a radiator ot' this character which has a core or body which presents `thc appearance of having individual square tubular cells or air passages but which is constructed of corrugated sheets of metal, thereby materially reducing the cost of the radiator the efficiency and capacity of an individual tube radiator. "In the accompanying drawings `consisting of 3 sheets: Figure l is a front elevation of a radiatm embodying myA invention. Fi". 2 is a fragmentary front elevation ot the radiator,on an enlarged scale, and showing the filling between the corrugated strips omitted. F'g. 3 is a fragmentary vertical section, an an enlarged scale, in line 3*3.-

Fig. 4. Figs. Ll and 5 are horizontal sections in the eorrespoiulingly numbered lines in Fig. l. Figs. and 'i' are vertical sections, on the same scale as Figs. et and 5, taken in'lines 6-(S and 7-7, Fig'. Fig, 8 is a fragmentary perspective view ot` tw companion corrugated strips ot av tier ot' cells or tubes. Fig. 9 is a view similar t'o Fig. 8 Showing a slight modification of my inventin from that shown in Figs. ift.

Similar letters o'l ret'erence indicate cor 'esponding parts throughout the several views. A represents the upper header or water receiving box which connects with the outlet of the engine coolingy system and 1i the lower header or water delivery box which connects with the inlet oi said system. Between said heads is arranged the cellular core or body of the radiator which embodies my invention and which is constructed as follows z-This core comprises a plurality of pairs of sheet 'metal strips each of which` is corrugated to yform a plurality of webs c which are arranged in line and a plurality of folded flanges (l which project laterally from one side of said strip and each 'of which has its folds connected 4at the base thereof with the adjacent longitudinal edges ot two webs. The. strips of a pair are assembled so that the crowns o't the iianges of one strip engage with the central parts of the webs of the companion strip between the flanges tlurcoi,'thereby forming a tier or series of external air tubes e which are square in cross section and which extend lengthwise from the front to the rear side of the radiator. At opposite ends of each' web the same is provided on 4its outer side with vertical (uitwardly projecting spacing beads which are adapted to engage with the corresponding beads on the webs of mljacent strips, thereby holding or spacing the several rows or tiers of tubes apart and forming internal vertical waterpassages g which extend from the underside ot'y the upper header to the upper side of the lower header. These beads f are preferably arranged `a short distance from the ends ot the webs so as to form -outwardly opening vertical grooves or channels i between the` ends oi,tlle webs ol adjacent strips. 'lho central Iparts o the folds of each flange preferably lie close togetherbut the ends oi these Jfolds are separated to :t'orln0 l`walls or lines between the several tubes which is so much sought after at the 'present time by the automobile trade.

In order to hold the webs of a coperating pair of strips reliably in posit-ion rela-V tively to each other, both while assembling or constructing the radiator and also while the same is in use, each ot the webs is proF vided at its ends and preferablyoutside of its vertical spacing bead with an outwardly projecting or delieeted locking seat or bead Zand cach flange is widened at its opposite ends so as to 'form laterally projecting locking lips or tongues m which enter the locking' seats of the webs. By this means the 'flanges and webs are held in place relatively to each other and the square formation of the air tubes is preserved; The several strips are secured to each other and to the headers preferably by soldering in the usual manner of building` radiators. If desired, the folds oflthe flanges may lic close t0- gether throughout their length, in which case 11o horizontal grooves are' formed at 'the4 'ends of these flanges, asshown inr Fig. 9.

As the water passes from the upper header downwardly through the verticalchannels into the lower header thesame is effectually cooled by the passage of the air through the horizontal tubes which present an exceptionally large coolingarea.

I claim as myinvention:

`1. A radiator comprising afpair of sheet metal strips each of which is 'corrugated to form a plurality of webs and laterally pro jecting -doubled flanges at the vopposing edges of said webs, the flanges of each stripeengaging with the Webs of' the other stripA between the Hanges of the latter so as to forni a plurality of tubes, the ends of the folds of each flan e being separated to forni ibing provided at their ends with outwardly A projecting spacing beads which engage with the corresponding beads of the webs of an I adjacent strip forming a groove between the saine and a filling arranged in said 3. A radiator comprising a plurality of pairs of sheet metal strips each of which is corrugated to form a plurality of webs which are arranged in line and laterally projecting doubled Hang-es at the 'opposing Aedges ofthe webs, the lianges of each strip of a pair engaging with the webs 4of the 'companion strip of the pair vbetween the flanges of the latter, the Webs of eachvstrip being provided at their ends' with outwardly projecting spacing beads which engage with the v'corresponding beads of the webs of an adjacent strip*v forming a groove between the ,5G

same and the ends of the folds of each flange being separated to form a groove bee tween the saine and a filling said grooves.
